Cryptojacking is a cyberattack where hackers use someone else’s computer or device to mine cryptocurrency without their consent or knowledge. They infect a victim’s computer with malicious software, usually through a phishing email or downloading infected software. To protect yourself from cryptojacking, you can take a few precautions: regularly update your operating system and all software, use a reliable antivirus program, be cautious of suspicious emails or websites, and consider using browser extensions that block cryptojacking scripts. Additionally, it’s important to avoid downloading software from untrustworthy sources and keep your browser extensions up to date.
